The Global Arbovirus Initiative, launched by the WHO, warns of the risks of exposure to dengue fever, chikungunya, zika and yellow fever and draws attention to the occurrence in tropical countries, such as Brazil, where more than 161,000 infections have been recorded this year
Last week, the World Health Organization launched the “Global Arbovirus Initiative”. The movement is global and alerts to the risks of exposure to viruses transmitted by arthropods (Arboviruses), which cause Dengue fever, Yellow Fever, Chikungunya and Zika – considered by the entity as threats to public health, in particular in tropical and subtropical countries, which bring together around 3.9 billion people.
According to the WHO, the incidence of cases, especially those of diseases transmitted by Aedes aegypti, is increasing considerably, as a result of ecological, economic and social factors. Here in Brazil, data presented in the Epidemiological Bulletin of the Ministry of Health indicates a 45% increase in dengue cases between January and March 12 of this year, compared to the same period last year.
The document also points out that in the first three months, more than 161,000 cases of arbovirus were recorded. In addition, it names the Center West region as the national leader in dengue incidence rate, followed by the North and South East regions. Also according to the report, Goiânia (GO), Brasília (DF) and Palmas (TO) are at the top of the ranking of the cities that have registered the most cases.
Although not at the top of the list, Campinas, inside São Paulo, has entered a state of disease alert. According to a survey by the Municipal Department of Health, currently 17 mapped neighborhoods present risks of dengue fever transmission and the concern to contain the proliferation of mosquitoes has prompted several popular awareness campaigns in the public network. In the private network, it is no different. At Grupo Sabin, for example, the investments are reflected in the updated portfolio, able to meet the demand of the population, thanks to its more than 7,300 types of laboratory tests, including PCR Combo, which detects with a sample only if you patient have dengue fever, chikungunya or zika, and this resulted in 7 working days.
Clinical pathologist Alex Galoro, head of the Sabin group in Campinas, explains that the laboratory also has a rapid test for dengue antigen (NS1 antibodies, IgG and IgM), with results up to 1 day open; detection and typing of the dengue virus by PCR, with results available within 7 working days and highlights the significant increase in the demand for tests during this first quarter.
“Our survey shows that more than 31% of tests were positive for dengue fever. This growth makes us redouble our attention and strengthen the orientation movements of individual and collective consciousness with the care that prevents the spread of the mosquito,” he says.
Galoro also details the importance of correct diagnosis for successful treatment. “An accurate report ensures the safety of the patient’s best course and helps the doctor to resolutely conduct the treatment, adequate assistance and timely adoption of measures, if there are indications of complications in the clinical picture” .
Mosquito control is everyone’s duty
Still according to the specialist, the main recommendation is to understand that “fighting Aedes aegypti is everyone’s duty and it starts at home. We can win this battle with basic care in our daily lives that doesn’t take so much time, like checking for standing water on roofs, gutters, bottles, tires, and environments that can serve as mosquito breeding grounds. It should also be mentioned that if it is necessary to store liquids, care must be taken not to leave the tanks uncovered, to prevent the mosquito from laying its eggs in these waters”.
The doctor also notes that regions with higher temperatures and higher rainfall have higher expectations for the number of breeding sites. “Mosquitoes proliferate in humid and warm spaces and regions with higher temperatures are quite favorable to Aedes,” he observes.
